light

Label

a) Crest

b) Wavelength

properties of wave

1. waves travel at speed of light 3 X 10 ⁸ m/s

2. Frequency - number of waves/ second (Hertz)

3. wavelength - distance from crest to crest

RELATIONSHIPS

1. wavelength and frequency are inversely proportional (when one goes up the other goes down)

2. frequency and energy are DIRECTLY proportional (when one goes up the other goes up)

3. RADIO WAVES: longest wavelength, lowest energy, lowest frequency

4. GAMMA RAYS: shortest wavelength, highest energy, highest frequency

5. red light has longest wavelength, lowest frequency and lowest energy

6. violet light has shortest wavelength, highest energy, and highest frequency
